https://www.scangauge.com/shop/scangaugeii/ SORRY FOR THE LONG POST! I took the one I was using in my V10 Ford motorhome and threw it in my R/T last summer. After watching my coolant temp and air intake temp, I scrolled on to the open/closed loop gauge. It is telling me open loop. I know Ryan sent me an open loop tune, but thought I was running a different closed loop tune. So, when I got home I installed a different tune. Still closed loop on the "scangauge". After driving I came home and installed a 3rd tune, same story, open loop. ANYWAY... Does anyone think the "Scangauge" is misreading my tuning??
